Well I finally finished building a new quad and put APM 2.0 on it, have to say I was very impressed, no PID changes needed, and very solid Alt hold. Did several test flights, everything on the board seemed to be functioning ok until I fitted an Attopilot current sensor to the board, after which I ended up with magic smoke from under the GPS sheild :( I have since found out that the sensor I attached is dodgy and supplied full battery voltage to the boards input. After close inspection of the board, after removing the sheild I can see one chip visibly burnt. It is marked with the leters JBR See photo:
So, what chip is this? is it easily available? and what are the chances of recovering this board?
When powered by USB all LEDs will light up, but the board is not recognised via USB
The other problem I have spotted on the board is another small chip marked G33 128 just next to the UART2 pads (this is probably not relevant now given the damage to the board)but it seems to have been misaligned on the board during assembly
So have I turned it into a desk ornament? or is it recoverable?
